Abstract

A device for lubricating a urinary catheter and for normally and automatically gripping the catheter but selectively releasing such catheter only when squeezing forces are applied by a user'"'"'s fingers during a catheterization procedure. Such a device is also combined with a protective container which preferably may also be used as a urine collecting pouch.

Claims

1. A catheter gripping and lubricating device comprising a deformable and shape-recoverable guide housing of elastomeric material having proximal and distal end portions and defining a lubricant chamber therebetween;

an end cap at said distal end portion;

lubricant retention means at said proximal end portion for retaining lubricant within said chamber;

said end cap having a central passage and said lubricant retention means having a coaxial aperture for sliding movement of a catheter therethrough as such catheter is advanced through said lubricant chamber of said housing; and

catheter gripping means in said proximal end portion of said housing for normally and automatically frictionally engaging opposite side surfaces of the catheter to restrain sliding movement thereof but being movable into catheter releasing positions only when said proximal end portion of said housing is squeezed by a user'"'"'s fingers to permit sliding movement of the catheter through said housing;

said gripping means including clamping members with opposing surfaces normally spaced closely together but capable of spreading apart into the catheter releasing positions.

2. The device of claim 1 in which said catheter gripping means is located proximally in relation to said lubricant chamber and said lubricant retention means.

3. A catheter package comprising a catheter gripping and lubricating device comprising a deformable and shape-recoverable guide housing of elastomeric material having proximal and distal end portions and defining a lubricant chamber therebetween;

an end cap at said distal end portion;

lubricant retention means at said proximal end portion for retaining lubricant within said chamber;

said end cap having a central passage and said lubricant retention means having a coaxial aperture for sliding movement of a catheter therethrough as the catheter is advanced through said lubricant chamber of said housing;

catheter gripping means in said proximal end portion of said housing for normally and automatically frictionally engaging opposite side surfaces of the catheter to restrain sliding movement thereof but being movable into catheter releasing positions only when said proximal end portion of said housing is squeezed by a user'"'"'s fingers to permit sliding movement of the catheter through said housing;

said gripping means including clamping members with opposing surfaces normally spaced closely together but capable of spreading apart into the catheter releasing positions; and

a flowable lubricant disposed in said chamber; and

a urinary catheter extending into said chamber through said aperture of said lubricant retention means.

4. The catheter package of claim 3 in which said catheter has a distal tip portion extending into said central passsage of said end cap.

5. The catheter package of claim 3 further comprising a generally flat pouch of flexible thermoplastic film;

said pouch having proximal and distal ends and said distal end portion of said housing being sealed to said pouch between walls thereof at the distal end of said pouch.

6. The catheter package of claim 5 in which said end cap includes a tubular extension projecting through and beyond said pouch at the distal end thereof.

7. The catheter package of claim 5 or 6 wherein said passage of said end cap is larger in diameter than an outside diameter of said catheter, whereby, lubricant applied to said catheter when the catheter is advanced through said lubricant chamber remains as a lubricant coating on said catheter as said catheter passes through said passage.

8. The catheter package of claim 6 wherein a tubular introducer is mounted on said extension externally of said pouch, said introducer having a distal end wall provided with at least one self-closing slit capable of opening to allow said catheter to be advanced therethrough, said tubular introducer having a longitudinal dimension sufficient to protect said catheter against contamination by organisms located in a patient'"'"'s urethra immediately adjacent the labia thereof.

9. A urinary catheter package comprising a catheter gripping and lubricating device comprising a deformable and shape-recoverable guide housing having a generally elliptical cross sectional shape defined by convexly curved opposite side walls merging along longitudinally-extending edges to define a lubricant chamber;

said housing having proximal and distal end portions at opposite ends of said chamber;

an end cap at said distal end portion;

lubricant retention means at said proximal end portion for retaining lubricant within said chamber;

said end cap having a axial passage and said lubricant retention means having an aperture coaxial therewith for slidably receiving a urinary catheter therethrough;

a urinary catheter extending into said chamber through said aperture of said lubricant retention means;

a flowable lubricant within said chamber; and

catheter gripping means in said proximal end portion of said housing for normally and automatically gripping said catheter to restrain sliding movement thereof but being deformable upon application of squeezing force by a user'"'"'s fingers against the curved side walls of said housing to release said catheter for sliding movement therethrough.

10. The catheter package of claim 9 wherein said catheter gripping means is located proximal to said lubricant retention means.

11. The catheter package of claim 9 in which said catheter has a distal tip portion;

said catheter normally being restrained against sliding movement by said gripping means with the distal tip portion thereof extending beyond said lubricant chamber and into said passage of said end cap.

12. The catheter package of claim 9 further comprising a generally flat pouch having side walls of flexible thermoplastic film and said catheter gripping and lubricating device is located therein.

13. The catheter package of claim 12 in which said pouch has a distal end portion internally sealed to said distal end portion of said housing.

14. The catheter package of claim 13 in which said end cap includes a tubular extension extending through said pouch at the distal end portion thereof.

15. The catheter package of claim 14 in which said passage of said end cap has a diameter larger than an external diameter of said catheter, whereby, lubricant applied to said catheter as the catheter is advanced through said chamber remains as a lubricant coating on said catheter when the catheter is advanced through the passage of said end cap.

16. The catheter package of claim 15 in which a tubular introducer is mounted on said extension externally of said pouch, said introducer being formed of elastomeric material and having a distal end wall provided with at least one self-closing slit capable of opening to allow said catheter to be advanced therethrough.

17. The catheter package of claim 9 in which said catheter gripping means includes a pair of deformable clamping members normally frictionally engaging opposite sides surfaces of said catheter, said clamping members extending between and being connected to said side walls of said housing;

whereby, the squeezing forces applied to said housing side walls causes said deformable clamping members to bow outwardly and release said catheter for sliding movement relative to said housing.

18. The catheter package of claim 17 in which said longitudinally-extending edges of said housing are displaced away from each other when said side walls of said housing are squeezed together;

said housing including connecting walls joining mid-portions of said deformable clamping members to said housing along said edges to cause said clamping members to bow outwardly and release said catheter for sliding movement when said side walls of said housing are squeezed together.

19. The catheter package of claim 17 in which said clamping members are each generally planar when in untensioned state prior to insertion of the catheter into said housing.

20. The catheter package of claim 9 in which said flowable lubricant is a lubricant gel.
